Nanoregulation in Berkeley:

Last month, the city of Berkeley became the first local jurisdiction to regulate nanotechnology as such. The New York Times reports that businesses within Berkeley that use nanoparticles measuring 100 nanometers or less in any dimension are required to file reports with local regulators. Interestingly enough, the regulation exempts the University of California and Lawrence Berkeley National Laboratory.

UPDATE: As initially drafted, I misakenly referred to the Lawrence Livermore Laboratory instead of the Lawrence Berkeley National Laboratory.
